Ultimate facepalm: just remembered that PayPal automatically provides my address to sellers and I never did update it when I moved so any Ebay purchases I've made since moving were shipped to Hay River. Nooooooooooooooooooooooooooooo!!!

Tiffany: Just go online and put in a short term change of address. Problem solved.

Me: Yes, but far more expensive than replacing the items that were shipped to the wrong address. My solution: contact all the sellers, get them to mail the parcel again once it's returned to them and bill me for the extra cost.
